ImageGear .NET v25.1 - Updated
ForwardDCT Method




ImageGear.Processing.Advanced Assembly > ImageGear.FreqIP Namespace > ImGearFrequencyProcessing Class : ForwardDCT Method
An ImGearComplexObject class object to be transformed.
Computes the forward Discrete Cosine Transform (DCT) of the input data.
Syntax
'Declaration
 
Public Shared Function ForwardDCT( _
   ByVal value As ImGearComplexObject _
) As ImGearComplexObject
'Usage
 
Dim value As ImGearComplexObject
Dim value As ImGearComplexObject
 
value = ImGearFrequencyProcessing.ForwardDCT(value)
public static ImGearComplexObject ForwardDCT( 
   ImGearComplexObject value
)
public: static ImGearComplexObject* ForwardDCT( 
   ImGearComplexObject* value
) 
public:
static ImGearComplexObject^ ForwardDCT( 
   ImGearComplexObject^ value
) 

Parameters

value
An ImGearComplexObject class object to be transformed.

Return Value

Remarks
This method computes the forward Discrete Cosine Transform (DCT) of the input data.

Before using this method, like other frequency processing methods, InitializeFFTW method must be called first to initialize the support for FFTW.

Can be applied only to valid ImGearComplexObject class object.

ImGearFrequencyProcessingVerifier.CanApplyForwardDCT method can be called to check whether the operation can be performed or not.
